Calibration Consideration
The most ideal pH ELECTRODE generates 0 mV at pH
7.00 ( 177.4 mV at pH 4 ) and meter has been always
calibrated with signals which simulate the most ideal pH
ELECTRODE ( based on 25 ambient environment ).℃
However not every pH ELECTRODE is as accurate as the
most ideal one, so calibration procedures are necessary
to be done before the first time measurement.
In addition to the first time measurement, users are also
recommended to execute the calibration procedures to
ensure the high accuracy measurement.
14

4)a. Immersed the probe to a depth at least 10 cm of
the measured liquid in order for the probe to be
influenced by the temperature & automatic
temperature compensation to take place.
26
b.As for the thermal equilibrium to occur between the
probe & the measurement sample must be allowed
to pass, which usually amounts to a few minutes if
the Temp. difference between the two is only
several Celsius degrees.
5)a. In order to measure the dissolved oxygen content in
any given liquid, it is sufficient to immerse the tip of
the probe in the solution, making sure that velocity
of the liquid coming into contact with the probe is at
least 0.2 - 0.3 m/s or to shake the probe.
b.During laboratory measurements, the use of a
magnetic agitator to ensure a certain velocity in the
fluid is recommended. In this way, errors due to the
diffusion of the oxygen present in the air in the
solution are reduced to a minimum.
6)Display will show the Dissolved Oxygen values ( mg/L )
at the same time the left bottom display will show the
Temp. value of the measured solution.
7)Rinsed the probe accurately with normal tap water after
each series of measurement.
Oxygen in the air
When the display unit show " %O2 ", it show the
air Oxygen value approximately.
Change the Temp. unit to ℉
If intend to change the Temp. unit from to ,℃℉
please refer page 37, chapter 9-6 ( Temp. Unit

"% Salt" compensation value adjustment
If intend to change the % Salt compensation value,
refer page 38, chapter 9-8 ( % Salt Compensation
value Setting ).
"Height" compensation value adjustment
If intend to change the Height compensation value,
refer page 39, chapter 9-9, 9-10 ( Height Compensation

7-2 Calibration
1)Install the " Probe Plug " ( 6-1, Fig. 4 ) into the
" DO Socket " ( 3-13, Fig. 1 ).
2)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Select the measurement mode to " Dissolved Oxygen
measurement ", the Display will show " mg/L " indicator.
Pressing the " Function Button " ( 3-6, Fig. 1 ) once
until the right bottom display show " %O2 ".
3)Wait for approx. 5 minutes at least until the
display reading values become stable & no
fluctuation.
4)Use the two fingers to press the " REC Button " ( 3-4,
Fig 1 ) and HOLD Button " ( 3-3, Fig. 1 ) at the same
time, the display will show the following screen as
example, release the both fingers.

5)Press the " Enter Button " ( 3-4, Fig. 1 ), the Display
.
value will count down from 30 to 0, then return to
normal measuring screen and finish the calibration
procedures. The complete calibration procedures will
take 30 seconds approximately.
After finish the calibration, press the " Function
Button " ( 3-6, Fig. 1 ) once, to let Display unit to
return " mg/L ".
Calibration Consideration :
a.As the oxygen in air is 20.9 % typically, so use
the environment air oxygen value for quick &
precise calibration.
Please process calibration procedures under
b
wide and ventilating environment for best effect.
7-3. Probe maintenance
User first time to use the meter :
Intend to let the DO probe keep the best
condition, when user receive the Oxygen Probe,
it should fill the Probe's Electrolyte at first.
User already use the probe for a certain
period :
Whenever user can not calibrate the meter
properly or the meter's reading value is not stable,
please check the oxygen probe to see if the
electrolyte in the probe head container is run out
or the diaphragm ( probe head with diaphragm
set) exist problem ( dirty ). If yes, please fill the
electrolyte or change the " Probe head with
diaphragm set " and make the new calibration.
29
The consideration of diaphragm ( probe head
with diaphragm set ) :
The oxygen probe component is the thin Teflon
diaphragm housed in the tip of the probe. The
diaphragm is permeable by the oxygen molecules but
not by the considerably larger molecules contained in
the electrolyte. Due to this characteristic, the oxygen
may diffuse throughout the electrolyte solution
contained in the probe, and its concentration may be
quantified by the measurement circuit.
This sensitive diaphragm is rather delicate & is easily
damaged if it comes into contact with solid objects or is
subjected to blows. If the diaphragm is damaged or the
electrolyte is run out, it must be replaced in the following
way :
Probe-filling Electrolyte,
OXEL-03
Probe head with diaphragm set
1)Unscrew the " Probe head " ( 7-3, Fig 5 ).
2)Pour out the old Electrolyte from the
container of the " Probe head ".
3)Fill the new Electrolyte ( OXEL-03 )
into the container of the " Probe
head " .
30
4)Screw the " Probe head " ( 7-3, Fig 5 )
)
into the probe body.
When not use the
5
probe, should insert
the " Probe head "
into the " Probe 7-1 Probe handle
protection cover " 7-2 Temp. sensing metal
